CUTTER-BAR FOR MOIWING-MACHIINES.

SPECIFICATION forming part of Letters Patent No. 525,114, dated August 28, 1894.

Application filed April 10, 1894.. Serial No. 507,075- (No model.)

Machines, of which the following is a specifi-.

cation.

My invention relates to improvements in attaching the cutting knives to the cutter bar and the mannerof operating them.

The object of my invention is to construct a machine that can be operated with less power than is now required by the machines in general use. That a single knife or cutter can be readily removed when to be repaired or sharpened without removing the entire cutter or scythe.

The accompanying drawings are referred to and made part of this specification.

Figure 1. shows my invention attached to the machine and Fig. 2 shows a cross section through the cutter.

In the drawings, A is the plate of the cutter bar; B, the sliding bar; 0, knives; D, a bar that holds the knives; E and F, guards; G G, projections forming a groove or sluice for sliding bar B. to pass to and fro.

a a are projections or cogs on sliding bar; b, thumb screw; 0 0, set screws; 01 (1, posts; e e e are holes in bar D; fff. a slot in knives.

The knives O. are attached to barD by posts (1 passing through theknives as shown, on which the knives are swung back and forth by sliding bar B. which is attached to and operated by the pitman rod. Bar D. holdsthe knives onto posts (1. d. and set screwsc Q can be adjusted in plate A. to allow the proper play of the knives on posts (I. (1. Bar D is held down upon the knives by the thumb screw b.

To removea knife for grinding or-for any other purpose it is only necessary to remove bar D. and lift the knife off of post d. This I claim to be of great advantage when a knife is broken as only one knife need be removed and a new knife inserted. To operate the knives when mowing grass requires much less power by the manner shown than by the old method and a better shear cut is obtained which is a recognized advantage in mowing machines.

The operation of my invention is as follows: The sliding bar 13., attached to the pitman rod moves back and forth in the sluice G. G. Projecting from bar B are cogs a. a. matching. into slots f. f. in the ends of the knives causing the knives to swing on posts 01 cl. the sharp end of the knife swings back and forth in the slots of guards F.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- In a mowing machine, the combination of the portable knives G operated by the bar B and pivotally attached thereto, with the bar D adapted to hold said knives in position by the use of a thumbscrew, and adjustable to allow the proper play of the knives by set screws 0 c, substantially as set forth.
